Reconstruction of Blast-Induced Vibrations in Adjacent Tunnels

Engineers have developed a new method to predict blast-induced vibrations in adjacent tunnels. The technique is based on reconstructing an "equivalent single-source waveform" from actual vibration measurements. This advancement is crucial for the safety and planning of underground construction projects, where blasting is a common practice for excavation but can generate vibrations harmful to nearby structures or existing tunnels.

The proposed method uses an inversion approach, where measured vibration data are employed to infer the characteristics of a simplified blasting source. By modeling the complex interaction of multiple explosive charges as a single equivalent source, the prediction process is simplified without sacrificing accuracy. This allows engineers to more efficiently assess the risk of structural damage and optimize blasting parameters to minimize environmental impact.
